English term or phrase: hard water

Definition from antoine.frostburg.edu:
Hard water is water contaminated with compounds of calcium and magnesium. Dissolved iron, manganese, and strontium compounds can also contribute to the "total hardness" of the water, which is usually expressed as ppm CaCO3. Water with a hardness over 80 ppm CaCO3 is often treated with water softeners, since hard water produces scale in hot water pipes and boilers and lowers the effectiveness of detergents.

Example sentence(s):

Some laundry detergents do not produce as many suds in hard water, these are likely to be soap-based products and do not work as well in hard-water as detergent based products. water-treatment.org.uk
Hard water also contributes to inefficient and costly operation of water-using appliances. Heated hard water forms a scale of calcium and magnesium minerals that can contribute to the inefficient operation or failure of water-using appliances. Wilkes University
Clothes washed in hard water often look dingy and feel harsh and scratchy. sciLinks

Notes to answerer

становится немного яснее, если can rely on the law of the country перевести как "может сослаться на законодательство (право) страны, в которой..."
